Hybrid form of quantum theory with non-Hermitian Hamiltonians

Miloslav Znojil

In 1956, Freeman Dyson discovered that the practical solution of Schrödinger equation may be facilitated when one replaces the standard self-adjoint Hamiltonian $\mathfrak{h}=\math…

Interference of non-Hermiticity with Hermiticity at exceptional points

Miloslav Znojil

A family of non-Hermitian but $P T -$ symmetric $2 J$ by $2 J$ toy-model tridiagonal-matrix Hamiltonians $H^{(2 J)} = H^{(2 J)} (t)$ with $J = K + M = 1, 2, \dots$ and $t < J^{2}$ is studied, fo…
